1990年马来群岛区域海岸线

该数据范围为马来群岛海岸线数据，海岸线类型共为12类，该分类体系还考虑了马来群岛区域岸线丰富的特点，专门制定了一套重点目标分类系统。该分类系统对经济价值高同时对近海水质影响较重的养殖区域进行了细分，并将生态价值不同的自然岸线细分为基岩岸线、淤泥质岸线、红树林岸线，将脆弱性和生态功能不同的人工围堤细分为交通围、码头围堤、农业围堤、养殖围堤、建设围堤等。

This dataset covers coastline data of the Malay Archipelago, which includes 12 distinct coastline types. Considering the rich diversity of coastline types in the Malay Archipelago region, a dedicated key target classification system was specially formulated for this dataset. This classification system subdivides aquaculture areas that possess high economic value and exert substantial impacts on nearshore water quality. It further divides natural coastlines with differing ecological values into three categories: bedrock coasts, muddy coasts, and mangrove coasts, and categorizes artificial embankments with varying vulnerabilities and ecological functions into traffic embankments, dock embankments, agricultural embankments, aquaculture embankments, construction embankments, and other types.
